Especially the sides of the fingers, back of the hands, soles of the feet and the extensor sides of the forearms and thighs are affected.
Clinical featuresThis section has been translated automatically.
Slowly growing, coarse, usually painful, cutaneous-subcutaneously located node, which slowly increases along the fasciae and nerve cords. At the time of diagnosis, the tumor node is usually no larger than 5.0 cm. Later tendency to ulceration. Often the ulceration is in the foreground, so that the tumour can impress under the image of a non-healing ulcer. A specific feature is the spread along nerves and vessels and fasciae.
HistologyThis section has been translated automatically.
- Infiltrating growing, granuloma-like tumor of epithelioid and spindle-shaped cells, central necroses, vascular invasion, often involving tendons and fascia.
- Frequent expression of MUC4 protein; furthermore focal expression of S-100 protein and EMA (= Epithelial Membrane Antigen, also called MUC1)
